About

The Berlin module can be used to measure AC or DC currents in the range 0-10A. It come in two models. One with embedded intelligence and the other with just a I2C interface for interfacing a module with more intelligence (Amsterdam with special firmware) that can handle a maximum of eight current sensor modules and export a VSCP interface to the world.

Typical use can be sening if equipment is on, device failure detection, energy calculations etc ect.

The firmware can handle eight channels but only one is available for the selfcontained unit.

Set the time in seconds between which measurement events are sent for each channel.

Available channels

Register 40(0x28) - # available channels. Read only.

Different hardware modules can have different number channels. The available number of channels can be read in this register.

Channel high current level

Register 41(0x29) - MSB of high current reading for channel 0. Read/wite.
Register 42(0x2A) - LSB of high current reading for channel 0. Read/wite.
Register 43(0x2B) - MSB high of current reading for channel 1. Read/wite.
Register 44(0x2C) - LSB high of current reading for channel 1. Read/wite.
Register 45(0x2D) - MSB high of current reading for channel 2. Read/wite.
Register 46(0x2E) - LSB high of current reading for channel 2. Read/wite.

Register 56(0x38) - LSB high of current reading for channel 7. Read/wite.

Voltage for power calculations

This is a signed long representation of a current voltage value. It is stored with a defined action or by configuration g the value. The value is the voltage * 100. It is used to send out the power measurement event using P=U*I.
